Functions

func AttributesFilterQueryForSelectBuilder

func AttributesFilterQueryForSelectBuilder(sl squirrel.SelectBuilder, filter *base.AttributeFilter) squirrel.SelectBuilder

AttributesFilterQueryForSelectBuilder -

func AttributesFilterQueryForUpdateBuilder

func AttributesFilterQueryForUpdateBuilder(sl squirrel.UpdateBuilder, filter *base.AttributeFilter) squirrel.UpdateBuilder

AttributesFilterQueryForUpdateBuilder -

func BulkEntityFilterQuery

func BulkEntityFilterQuery(tenantID, entityType string, snap uint64) string

BulkEntityFilterQuery -

func GenerateGCQuery

func GenerateGCQuery(table string, value uint64) squirrel.DeleteBuilder

GenerateGCQuery generates a Squirrel DELETE query builder for garbage collection. It constructs a query to delete expired records from the specified table based on the provided value, which represents a transaction ID.

func NewContinuousToken

func NewContinuousToken(value string) database.ContinuousToken

NewContinuousToken - Creates a new continuous token

func Rollback

func Rollback(tx *sql.Tx)

Rollback - Rollbacks a transaction and logs the error

func SnapshotQuery

func SnapshotQuery(sl squirrel.SelectBuilder, value uint64) squirrel.SelectBuilder

SnapshotQuery adds conditions to a SELECT query for checking transaction visibility based on created and expired transaction IDs. The query checks if transactions are visible in a snapshot associated with the provided value.

func TuplesFilterQueryForSelectBuilder

func TuplesFilterQueryForSelectBuilder(sl squirrel.SelectBuilder, filter *base.TupleFilter) squirrel.SelectBuilder

TuplesFilterQueryForSelectBuilder -

func TuplesFilterQueryForUpdateBuilder

func TuplesFilterQueryForUpdateBuilder(sl squirrel.UpdateBuilder, filter *base.TupleFilter) squirrel.UpdateBuilder

TuplesFilterQueryForUpdateBuilder -
